ROLLER SKATE.

Application led March 29, `1926. Serial No. 98,161.

This invent-ion relates generally to roller skates, the invention having more particular reference to a novel type of electrically driven roller skates.

The invent-ion has for an object the pro-` vision ofv an improved electrically driven roller skate embodying adjustable members so as to insure a good fitting device.

A further object of the invention is to provide a braking means, so as to prevent accidents. y

Another object of the invention is to provide an electrically driven roller skate which maybe readily and easily steered.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claimsl in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawing shows my improved electrically driven roller skate` and attachments, as it would appear applied to the skater.

Fig. 2 of the ldrawing shows a side elevational view of my improved electrical driven roller skate, certain parts being removed to show more clearly the working parts.

Fig. 3 is a top plan detail view of the adjustable members, as used in connection with my improved electrically driven roller skate.

Fig. 4 is a side elevational view of the parts as shown in Fig. 3.

Fig. 5 is a fragmentary vertical sectional View taken 0n the line 5 5 of Fig. 3.

As here embodied my improved electrically driven roller skate comprises a heel element 10, and sole element 11', adjustably attached thereto. The heel element is provided with an extended portion 12, adapted to engage the heel of the shoe, at the rear. The rear wheels 13, preferably provided with rubber tires 14, vulcanized or otherwise attached thereto, are rigidly attached to the shaft- 15, which is rotatively mounted in bearings 15', rigidly attached to the heel element 10. The front wheel 16, preferably provided with a rubber tire 17, vulcanized or otherwise attached thereto. is rotatively mounted in a bracket 18, which is pivotably attached to the said sole element 11, as at 19. The bracket 18 allows the front wheel 16 to act as a caster, so as to effect easy steering. The electric motor 20, of common construction, is rattached to the heel element 10, and 1sl operatively connected to a train of reduction gears 21, so as to drive the rear wheels 13, the gear 22 being rigidly attached to the shaft 15 and meshing with the train of reduction gears.

.Referring in. particular to Fig. 1 of the vaccompanying drawing, the battery 23 is carried in a case 24, which is provided with a strap 25 and buckle 26, adapted to be strapped around the waist of the skater. -A rheostat 27, or any device for varying the speed Aof the electric motor 20, is attached to the case 24. The battery 23, the rheostat 27,

and the electric motor 20, are connected by the electric wires 28, of common insulated construction, the electric wires 28 being coiled, or loopedLas designated bythe reference numeral 29, so as to permit` the skater to bend his knees, without interfering with the electric wires or the connections thereto. The electric wires are also attached yto the clothing of the wearer, as may be required, by suitable pins, clips, or the like, as designated by the reference numeral 30.

The bra-ke arm 31 is rigidly attached at its upper extremity to the heel element 10, and

extending downward therefrom, so as to permit. of engagement with the ground or floor when my improved roller skate is tilted upwards at the front, as a means of slackening the speed or stopping. The skater will lat the same time shut off the current of the electric motor by means of the rheostat.

Referring in particular to Figs. 3 and 4 of the accompanying drawing, the sole element 11, is provided with an elongated slot 33, suitably located near the rear thereof, as a means of adjustably attaching the same to the heel element 10, by a bolt or any similar means. The side clampsv 34 and 35, are provided with outer extended extremities 36, adapted to engage the sides of the shoe of the skate, and have serrated or notched edges 37, as a means of holding the said side clamps 34 and 35 in any desired extended position. The side clamp 34 is also provided with protruding portions 38, relatively located, and engaging with the serrated or notched portion 39 of the front clamp 40, which is provided with an outer or front extended extremity 41, adapted to engage the toe 0f the skaters shoe, and is also provided with an elongated slot 42, as a means of attaching same to the sole element ll', by the bolt 43 located in the said elongated slot 42 and in anA aperture suitably located in the sole element 11, the front clamp 40 being also provided with a second elongated slot 44, so as to prevent interference with the hereinbefore mentioned bracket 18, not shown in the above referred. te drawings the bracket 18 being engageable in aperture 19. The said side 'clamps 34, and 35, are positioned and clamped between the sole element ll and the front clamp 40 by the action olf bolt 43 so that they remain as set. As shown on the drawing the first one of the projections 38 engage the serrations 59y but bolt 43 may be loosened and side clamp 34 moved so that the first one of the projections 38 is past the serrations 89, and the second one engages the serrations", o'r so that the first andl second are past tie serrations and the third one engages the serrations.

While l have above described the preferred form, construction and arrangement of the several elements employed, it will be understood that the device is, nevertheless, susceptible of considerable modification therein, and l therefore reserve the privilege of resorting to all such changes as may be fairly embodied within thespirit and scope 'of the invention as claimed.

Having thus described my invention what l ll claim as new and desire to protect by Letters Patent of the United States is as follows 1. ln a device of the class described, a forward element provided with an elongated slot, located at the rear, side clamps provided Twith outer, extended extremities, adapted to'engage' the sides of the shoe, said Lide clamps having serrated edges as a means oi holding the said side clamps in'any desired extended position one of the said side clamps provided with' protruding portions, engaging with a serrated pe'rton ot a front clamp provided with a front extended extremity, adapted to engage the toe of the ner/avec slice, and also provided with an elongated slot, as a means of adjustably attaching the said front clamp to the said front element.

2. In a device of the class described a skate comprising a foot plate, side gripping member having toothed edges slidably mounted on said foot plate comprising upwardly and inwardly turned projections for engaging the sole of a shoe, said side gripping members being adapted to be fixed in position by interlocking oit said toothed edges, a toe Igripping member having a plurality of openings therein slidably mounted on said ioot plate, and a depending projection on one of said side gripping members adapted to be inserted in any desiredA opening of said toe member for retaining the latter in a fixed position of extension.

3. In device. of the-class describech a skate comprising a ioot plate, an extension having spaced longitudinal slots therein slidab'ly mounted on said 'foot plate, bolts mounted on foot plate and disposed through the spaced slots in said extension for adjustably securing said extension' in said foot plate, a projection on said extension disposed upwardly and rearwardly for gripping the toe portion oi the sole of a shoe, lateral ex'- tensio'n comprising upwardly and inwardly disposed extensions for gripping the. side portion of the sole of a shoe slidably mounted between the bottom of saidfoot plate and the upperl surface of said longitudinal extension, teethl on the adjacent edges of said lateral extensions adapted to be interlocked for retaining said extensionsy in a fixed relation, and a projection on one of said lateral extensions adapted to be engaged in any one of a series of openings in said longitudinal extension for preventing movement of said longitudinal extension relative to said lateral extension.`

In testimony whereof lhavefatfixed my signature.
